TransCanada says their Keystone pipelines are the safest on the continent.

But what about those 12 spills in the past year? Since its operation began in June of 2010, the Keystone 1 pipeline has suffered more spills than any other 1st year pipeline in U.S. history, a track record which does not bode well for the proposed Keystone XL which tracks across one of the largest aquifers in the world – the Ogallala – which supplies drinking water to millions of mid-Westerners and provides 30% of the nation’s groundwater used for irrigation.
